RUBBING-DOWN DEVICE FOR MOUNTING PHOTOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 375,820. dated January3, 1888.

I Application filed October 3, 1887. Serial No. 251,318. (No model.)

To all whom it may concern:

Beit known that I, CHARLES S. HOWLAND, residing at Campville, in thecounty of Litchfield and State of Connecticut, have invented certain newand useful Improvements in Rubhing-Down Devices for MountingPhotographs; and I do declare the following to be a full, clear, andexact description of the same, ref` erence being had to the accompanyingdrawings, which form a part of this specification.

My invention relates t0 an improvement in rubbing-down devices formounting photographs, the object being to produce a portable articlecombining cheapness and simplicity of construction with convenience,durability, and efficiency in use.

With these ends in view my invention consists in a rubbing-down devicehaving two rolls, a strip of cloth attached to and wound upon them, andmeans, includingaspring, for equalizing their action.

My invention further consists in a rubbingdown device having two rolls,a strip of cloth attached to and wound upon them, and gearing connectingthem and including an equalizing-spring.

My invention further consists in certain details of construction andcombinations of parts, as will be hereinafter described,and pointed outin the claims.

In the accompanying drawings, Figure] is a plan view of a rubbing-downdevice constructed in accordance with my invention. Fig. 2 is a viewthereofin side elevation. Fig. 3 is abroken sectional view showing theequalizing-gearing. Fig. 4 is a detached view, in outside elevation, ofthe loose inner pinion. Fig. 5 is a similar View, in inside elevation,of the loose outer or lianged pinion; and Fig. 6 is a detached View ofthe equalizing-spring.

As herein shown the device consists,in part, of two parallel rolls, AandB, connected by a long strip, C, of muslin or other fabric, which iswound upon them and journaled in the outer ends of two framepieces, D D,rigidly secured to the opposite ends of a shaft, E, mounted to turnfreely in a yoke or frame, F, having an operating-handle, G, attached toit, as shown. A pinion, I-I, secured to one end of the roll A,

5o meshes into a loose pinion, I, mounted upon the shaft E, and providedupon its outer face with a hub, J, furnished with a finger, K, engagedby the perforated inner end of a spiral spring, L, having its outer endbent to engage with a pin, M, located near the periphery ofa pinion, N,also loosely mounted upon the shaft E, provided with an inwardly-projecting flange, O, inclosing the said spring, and meshing with apinion, P, rigidly Secured to the roll B, as shown.

The described gearing connect-ing the two rolls prevents them fromturning under the weight of the strip, as would otherwise result. Thespring equalizes their action when they rotate at different rates, owingto being virtually different in size by an unequal division of the stripbetween them. When the two rolls rotate alike,the pinions I and N rotateas one pinion. When, on the other hand, the rolls rotate at differentrates, the spring winds or unwinds, according to the direction of theirrotation, permitting the pinions I and Nto rotate independently andcompensate for the different rotations ofthe rolls. Then, as soon as thedevice is lifted to relieve the rolls of the friction between them andwhatever they may be resting upon, the spring recovers and turns themand draws the strip taut between them. The shaft E being mounted to turnfreely in the yoke, the rolls readily conform in inclination to thesurface over which they are passed, and both rolls may be rotated aroundsuch shaft as a center. y

In using the device it is placed upon the photograph or other article tobe rubbed down and passed hack and forth over the same, the rollsrotating, and hence unwinding the strip from one roll and winding itupon the other. When the strip becomes soiled in one part, the rolls arerotated to shift it to expose it where unsoiled.

I would have it understood that I do not limit myself to the exactconstruction herein shown and described, 4but hold myself at liberty tomake such change and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A rubbing-down device for mounting photographs, having two rolls,astrip of clot-h attached to and wound upon them, and means, including aspring, for equalizing their action, substantially as set forth.

2. A rubbing-down device for mounting photographs, having two rolls, astrip of clot-h attached to and wound upon them, and gearing connectingthem and including an equalizingspring, substantially as set forth.

3. A rubbing-down device for mounting photographs, having two rolls, astrip of cloth attached to and wound upon them, a pinion attached toeach roll, two independent pinions respectively meshing into the pinionssecured to the rolls, and a spiral spring coupling such independentpinions and winding or unwinding to equalize the action of the rollswhen they rotate at different rates, substantial] y as' set forth.

4. A rubbing-down device for mounting photographs, having two rolls, twoframe pieces in which they arejournaled, a sha-ft to which suchframe-pieces are secured, a yoke carrying such shaft and provided with ahandle, and means for equalizing the action of the rolls, substantiallyas set forth.

In testimony whereofl have signed thisspccication in the presence of twosubscribing witnesses.

CHARLES S. HOWLAND.
